Gas chromatograph (vertical)

GC912 Gas chromatograph (vertical)

Features:

1. The GC912 series can only be equipped with a single commonly used detector (except FPD).

2. LCD screen display, full microcomputer control system, a single computer can control up to 253 chromatographs, with 7-channel temperature control system and 8-channel external event time program.

3. The instrument uses an RJ45 network cable output interface, which makes control and acquisition simple and convenient, and can realize remote control of the instrument and remote data transmission, processing and supervision. Can be connected to unit supervisors and superior supervisors to facilitate supervision by supervisors.

4. The instrument has a built-in chromatography workstation, which has functions such as intelligent peak identification/automatic processing, multi-channel spectrum integration and exchange processing, etc.

5. The column oven has an automatic rear door opening for rapid cooling, and can carry out 8-step program temperature rise. The column oven has a near room temperature control function (5℃ above room temperature).

6. It can be configured with packed column injector, capillary column injector, gas valve injection, ballast reforming furnace and other devices.

7. It has a fault self-diagnosis function, which can display the fault location and nature at any time. It has an over-temperature protection function. When the temperature exceeds the set temperature, it will automatically stop the force. Heat and alarm.
